AI Technical Summary
Existing superhydrophobic coatings are inadequate in terms of durability and spray uniformity, and cannot meet the service life requirements of engineering applications.
A modified nanoparticle dispersion was used to modify the nanoparticles with fluorinated siloxanes and azo epoxy siloxanes, and combined with dispersion and ultrasonic treatment to prepare a superhydrophobic coating topcoat, which was then sprayed onto the substrate surface to form a coating.
It significantly improves the bonding stability between the coating and the substrate, enhances the weather resistance and wear resistance of the coating, maintains efficient superhydrophobic properties, with a water contact angle of 105° and an oil contact angle of 159°, and performs excellently under mechanical friction and UV aging conditions.
